Let me say, I started with wine then progressed to wine and vodka, not in the same drink, but vodka by myself, then wine with the wife, to keep up appearances. Though she knew something was off.
It progresses. Nip it as soon as possible.
I couldn't stand to throw anything away, though I generally couldn't keep my hands off any booze in the house, so we never had any sitting around. If you can't throw it away and it's good quality, give it away to a normal drinker.
